摘要： A preform gate cutter for cutting a hole in a preform gate includes a cutter, a housing forming a cutting chamber, and a preform chuck having a longitudinal preform bore for receiving a preform. The preform chuck is insertable into a housing bore. The preform chuck defines a centerline that is coincident with the preform centerline and is aligned with a perimeter of the cutter to enable the cutter to form a hole in the preform at the preform gate. The housing may have a cutting chip discharge slot. A method for cutting a hole at the preform gate is also provided.

摘要： An apparatus and method for supplying a printed circuit board to a printed circuit board drilling machine and for returning the printed circuit board after the drilling. A stocker stores a plurality of printed circuit boards in a tilted state, and a plurality of conveyor rollers provides a conveying path for the printed circuit boards. A conveyor device which includes conveyor rollers provides a conveying path connected to the first mentioned conveying path. The arrival of the printed circuit board is detected at a predetermined position, and the printed circuit board is then decelerated by braking in response to a signal from the detection. A device is provided on the printed circuit board drilling machine for delivering the printed circuit board to the printed circuit board drilling machine. A base plate can be provided with a pair of locating pins for being anchored to the drilling machine table and has the printed circuit board mounted thereon so that the drilling machine can handle one pattern and number of location pins regardless of the number and pattern of fixing pins on the printed circuit board.
